SPECIFICATION forming part of Letters Patent-No. 415,025, dated November12, 1889.

I Application filed September 15, 1888. Serial No. 285,455. (No model.)

.To @ZZ wiz/0m it may concern:

Be ig known that we, THOMAS H. QONLEY and JAMES ANDREWS, of AWare, inthe county of Hampshire and State of Massachusetts, have inventedcertain new and useful Improvements in Spinning-Mules, of which thefollowing is a specification.

In the operation` of vspinning-mules it is essential to the productionof perfect yarn that the follower and winding mechanism should operatein absolute unisonthat is, that the winding mechanism should be set inoperation simultaneously with the descent of the guide-follower andcease operation the instant that the follower is unlocked, and toaccomplish this desideratum by improved devices is the object of ourinvention.

Ourinvention will first be described in view of the annexed drawings,forming a part of this specification, and then pointed out in the claimshereto appended.

Of the drawings, Figure l represents a side elevation, partially insection, of so much of a mule-carriage andits equipments as is necessaryto explain the nature and design of our improvements, the latter beingshown in conn ect-ion therewith and the winding mechanism as out ofoperation. Fig. 2 is a View similar to Fig. 1, the winding mechanismbeing represented asin operation. Fig. 3 is a plan View of substantiallythe parts shown in Fig. l. Fig. 4 is a detail view of parts shown inFig. 3

.and hereinafter more particularly referred to.

h designates the followerleg, which is pivoted at its upper end to anarm i, secured to the guide-follower shaft f. The follower-leg isprovided on its lower end with an offset block j, which is adapted tocatch over the bowl or roller k (shown in dotted lines in Figs. landwhen the guide-follower is depressed and the winding mechanism is inoperation, as seen in Fig. 2, or be moved off from said bowl or rollerwhen the guide-follower is raised and the winding mechanism is out ofoperation, as seen in Fig. 1. The followerleg is drawn toward the bowlor roller 7c by means of a spring Z, connected at one end to the frameof the carriage, andA at the other to the free end of a short arm m,secured on a rock-shaft n, to which is also connected an arm o, which isconnected by means of alinkstrap p witli the follower-leg h.

q designates the backing-off chain, attached at one end to the free endof the backing-off finger r, connected with the guide-follower shaft f,said chain q passing around a pulley s and attached to the backing-offsnail t on the tindrum-shaft c.

The construction and arrangement of parts so far described are such asare usually employed in a large class of cotton-spinning mules, thoughit will appear obvious that the precise form and relationship shown ofsaid parts are not essential to our invention, nor, indeed, are all ofthe parts so far mentioned concerned in our improvements.

As has already been indicated, gearwheel bis constructed to turn looselyon shaft ct, and connected -with said gear and turning with it is aclutch part u, adapted to be engaged and driven by a clutch part(called, for the sake of convenience in this description, a slidingclutch part) @,splined on the shaft c, so as to turn the same, butmovable longitudinally thereon,so as to engage and be disengaged fromthe clutch part u, the two parts u and v comprising the clutch-boX, bywhich the winding mechanism is put into and thrown out of operation. Theclutch-box is so formed that the winding mechanism will be set inoperation the moment the sliding part t is brought into engagement withthe part u and be put out of operation the instant the two parts areseparated.

w is a lever (here shown as a bell-crank lever) fulcrumed on the frameof the carriage, one end of which lever extends into a groove formed inthe sliding clutch part o, and the other is connected by means of a linkwith IOO a pin or spindle y, upon which the pulley s is journaled,andwhich connects the arm o and link p, as hereinbefore described.

With this explanation it will be understood that when the guide-followerdescends to guide the'yarn in position on the cops and the follower-legis moved by spring Z to the position shown in Fig. 2, which is commonlycalled by mule-spinners the locking of the follower, lever w will beoperated throughthe medium of connecting-links p so as to slide clutchparte into engagement with part u, as shown in Fig. 4,immediatelysetting the winding mechanism in operation, and when theguide-follower rises or is unlocked and the follower-leg is moved fromthe position shown in Fig. 2 to that shown in Fig. l lever w will he sooperated as to separate the two clutch September, A. D. 1888.
